The ttsbegin, ttscommit, and ttsabort operators and the selectforupdate keyword were also introduced to show you how to create and handle a transaction scope.

In addition, we also went through the difference between the insert, update, and delete methods and the doInsert, doUpdate, and doDelete methods.

In the next chapter, we will use the knowledge gained in this chapter and look at how we can use it to integrate data with other systems. We do this by reading and writing text files and XML files in addition to other databases using an ODBC...
